ALFRED F. BARR-OW, OF NEW HAVEN, INDIANA.

WINDMILL.

Specification of Letters Patent.

Patented Feb. 28, 1911.

Application filed August 17, 1910. Serial No. 577,611.

To all whom it may concern:

Be it known that I, ALFRED F. BARROW, a citizen of the United States residing at New Haven, in the county of Allen and State of Indiana, have invented certainnew and useful Improvements in Windmills, of which the following is a specification reference being had to the accompanying drawings.

This invention relates to improvements in windmill gearing and has for its primary object to provide a very simple and eflicient mechanism whereby the pump rod actuating means is automatically rendered inoperative upon the occurrence of heavy wind storms thereby obviating the liability of serious damage to the gearing.

A further object of my invention is to provide means for reciprocating the pump rod when there is only a light wind, and with a minimum expenditure of power.

A still further object resides in the provision of a longitudinally movable windwheel and movable connections between the windwheel and a rudder vane, said connections being adapted to actuate a weighted arm which acts as a brake for the pump rod and operating gearing to stop the same, said rudder vane being simultaneously moved to a position in parallel relation to the windwheel.

With these and other objects in view, the invention consists of the novel features of construction, combination and arrangement of parts hereinafter fully described and claimed, and illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a windwheel, pump rod gearing and brake mecha nism embodying my invention; Fig. 2 is a top plan view thereof; Fig. 3 is an enlarged detail longitudinal section taken on the line 33 of Fig. 2; Fig. 4 is a section taken on the line A4.- of Fig. 1; and Fig. 5 is a detail perspective view of the connecting rod.

Referring in detail to the accompanying drawings 5 designates a mast or standard which is rigidly mounted in a tower of any approved construction, (not shown). A bearing 6 is horizontally mounted upon the upper end of the mast 5 and has an annular head plate 7 integrally formed with said mast on which the bearing is arranged.

A shaft or arbor 8 is rotatably mounted in the cylindrical bearing 6. A collar 9 is longitudinally adjustable on the arbor into engagement with the end of the bearing 6' and is adapted to overcome any tendency of the arbor to move longitudinally in said hearing. The end portion of the arbor 8 is square in cross section as shown at 8. This squared end portion of the arbor is received in the similarly shaped bore of a bearing sleeve 10. The sleeve 10, it will be observed, is of considerably less length than the squared portion 8' of the arbor 8 so as to provide a space between the collar 9 and the end of the sleeve 10. The sleeve 10 forms the hub of the windwheel 11. This wheel may be of any approved construction and forms no part of the present invention. The extremity of the shaft 8 on the squared portion thereof is reduced and screw threaded to receive a nut 12 which is of greater diameter than the shaft 8 and acts as a stop to limit the outward sliding movement of the wheel hub or sleeve 10.

Upon the end of the cylindrical portion of the shaft or arbor 8 which is mounted in the bearing 6, a circular head plate or wheel 13 is carried. As shown in the drawings this wheel has formed therewith the arms 13 which extend from a central body portion securely threaded or otherwise fixed upon the end of the shaft 8. The wheel 13 is formed with right angularly extending intersecting slots 14: and in these slots the guide members 16, carried by the connecting rod 15, are adapted to move. As shown in detail in Fig. 5 the guide members 16 are in the form of elongated blocks each having a head 16 formed on one end and a cylindrical stud 16 on the other end. These studs which are formed on the guide memhere are rotatably disposed in openings provided in the enlarged upper end portion of the connecting rod 15. Suitable keys 17 extend through the extremities of these studs so as to retain the same in said openings.

The lower end of the connecting rod 15 may be connected to the pump rod of the mill in any approved manner, and it will be obvious that as the windwheel is rotated, the rotation of the wheel 13 will cause the guide members 16 to move in the guide slots 14 of said wheel. With each half revolution of the wheel said members reverse their direction of movement in the slots. Thus it will be seen that upon each revolution of the wheel 13 there will be two complete strokes of the pump rod. In this manner the rod is E and in the operation of the device, the bar 31 reciprocated by a very light current of wind acting upon the windwheel and with a minimum expenditure of power. The center, or connecting point between the rod 15 and the wheel 13 is constantly changing, while with the usual crank or eccentric connections, the pivotal point is stationary. It will therefore be obvious that by means of my im-' proved gearing a very great reduction in the power necessary to reciprocate the pump rod is effected.

An arm 18 is integrally formed upon the end of the bearing 6 and depends therefrom. A horizontally positioned annular ring 19 is mounted upon ball bearings on the upper end of the mast 5. In this manner friction is reduced to a minimum in the rotation of the windwheel upon the mast. At a point diametrically opposite to the arm 18, a second arm is integrally formed with the annular member 19 and. a vertically disposed sleeve 20 is formed upon the upper end thereof. A pivot rod 21 is mounted to ro tate in the sleeve 20 and to the opposite ends of this rod the diverging arms 23 of a rudder vane 22 are rigidly secured.

A channel ring 2st is disposed in concentric relation to and is supported upon the hub 10 of the windwheel. A rectangular longitudinally movable bar 25 has one of its ends upturned and disposed in the channel of the ring 2st as indicated at 26. This bar 25 is movably supported by a vertical arm 27 formed upon one end of the bearing 6. The pivot rod 21 extends above the upper end of the sleeve 20 and has secured thereon an angular arm 28. The horizontal portion of this arm is bifurcated to receive the end of a T-shaped knuckle member 29 the other end of which is pivoted to the end of the bar 25. The members 28 and 29 are loosely connected for relative pivotal movement, the diverging arm 23 of the rudder vane 22 being rigidly secured to the member 28. A lug 30 is also formed upon the bearing 6 and to this lug one end of an L-shaped bar 31 is pivoted. Adjacent to its pivoted end the bar 31 is longitudinally slotted as shown at 32 and in this slot a roller 33 mounted upon a stud fixed to the bar 25 is adapted to move. Upon the other leg of the L-shaped bar 31 a weight 34: is longitudinally movable and is secured in its adjusted position by means of a set screw 35. Between the pivoted end of the bar 31 and the slot 32, a lug 36 is formed upon the edge of said bar. This lug is adapted to engage upon the periphery of the wheel 13 in the operation of the mechanism and acts as a brake for said wheel as will now be more fully described.

It is believed that from the above description the manner of assembling the various elements will be readily understood is normally disposed in the position indicated in the drawings, the weight 3% maintaining said bar in such position and overcoming any tendency of the bar 25 to move longitudinally in the arm 27. However, should a gale or heavy wind storm arise, the windwheel will be moved longitudinally upon the square port-ion 8 of the arbor 8, a space being provided as hereinbefore noted between the end of the hub 10 and the collar 9 to permit of such sliding movement. It will be obvious that upon this movement f the windwheel the bar 25 will also be moved and through the connecting knuckle 29 between said bar and the member 28, the rudder vane 22 will be swung into a position in parallel relation to the windwheel thereby preventing to a great extent the bodily rotation of the wheel and the gearing upon the mast 5. This movement of the bar 25 it will be observed, will also throw the bar 31 outwardly, overcoming the weight 3%. The lug or extension 36 carried by said bar will thus be forced downwardly into frictional engagement upon the periphery of the wheel 13, the roller 33 moving in the slot 32 of said bar. A chain 37 is connected to the bar 31 at one end and passes over a guide pulley 38 mounted on the annular member 19 whereby the brake device may be manually actuated if desired to stop the reciprocation of the pump rod. The braking action thus induced upon the wheel 13 will gradually overcome the rotative movement of the wheel and stop the reciprocatory movement of the pump rod. Thus the mechanism is rendered inoperative and danger of break age of the various parts owing to the violence of their action caused by heavy winds, is entirely overcome.

From the foregoing it is believed that the construction and operation of my improved windmill gearing will be readily understood. The mechanism is comparatively simple and it is also extremely efficient and highly durable in practical use.

While I have shown and described the preferred construction and arrangement of the various parts, it will be understood that the invention is susceptible of a great many minor modifications without departing from the essential feature or sacrificing any of the advantages thereof.
